MACHINE FOR WINDING TAPERING COPS.

SPECIFICATION forming part of Letters Patent No. 593,756, dated November 16, 1897.

Application filed November 28,1893. Serial No. 492,264. (No model.)

Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Machines for Winding Tapering Cops, of which the following is a specification.

My invention relates to the manufacture of cops of the general character set forth in my Letters Patent Nos. 486,745 and 480,157, describing the machine for making such cops; and my invention consists in an apparatus for winding tapering cops, as fully set forth hereinafter and as illustrated in the accompanying'drawings, in which Figure 1 is an elevation of my improved apparatus. Fig. 2 is a transverse sectional elevation; Fig. 3, a detail in section. Fig. 4 is a face view of Fig. 3.

The frame A is of any suitable character and supports the cam-shaft b, the Windingshaft a, and bearings for one or more gears 3,

between apinion 1 on the winding-shaft and a gear 2 on the shaft 1), but in this case 'having a movement independent thereof to a slight extent. The driving-pulley is connected with one of the gearsas, for instance, with the gear 1. Upon the shaft 19 is a cameylinder e, having a cam-groove 9, into which enters a pin g upon a sliding frame B, sliding on transverse rods 20 20 and carrying two guide-rods 17 17 at right angles to the rods 20 20, upon which rods 17 slides a frame 0, carrying the thread-guide c. A spring it tends to throw the frame C inward and maintain the upper portion of the guide in constant contact with the cop as the latter is wound.

The cop-holder is generallya tube or cylinder 21, which is held between suitable clamps or supports 22 22. As it is necessary to insert and remove these holders, one of the holders 22 is secured to the end of the shaft or and the other is secured so as to revolve freely on the end of a rod 23, sliding in the frame and operated by a handle D.

In order to secure an additional movement to the winding-shaft at each reciprocation of the guide 0, as is necessary in winding cops in accordance with my before-described patout, I provide means whereby one of the gears is advanced or retarded in respect to the motion of one of the shafts b a. For instance, the gear 2, instead of being secured fixedly upon the shaft b, is mounted so as to turn thereon, and is provided with a flange having a rack 5 at the edge, and with this rack engages apinion 14 on a shaft 13, carried by a bracket J, secured to the shaft-b, and means are provided for slowly turning the shaft 13 of the pinion 14 as the shaft b revolves, so that the gear 2 is revolved either to a slightly greater or slightly less extent than the said shaft. The revolution of the shaft 13 is effected by providing it with a friction-Wheel 15, that bears upon a plate 16. It will not be necessary to go into further details of the construction and operation of these features of this machine, as they are fully set forth in my Letters Patent No. 506,959.

It has proved to be desirable for many purposes to wind cops of a conical form, and in order to accomplish this result I make use of tapering or conical holders, winding thereon in the same manner as when the said holders or cop-tubes are cylindrical. It is essential, however, in order to wind in accordance with my aforesaid Letters Patent, that the eye or guiding-notch of the guide shall be maintained at right angles to the face of and in close proximity to the surface of the cop, as it increases in size and at every point of travel of the guide.

It will be evident that a rigid guide arranged with its face parallel to the axis of the holder would bear at one side upon the surface of a tapering or conical cop, while the other side would be free from contact with the said surface and the mouth of the eye or guide would not be in close proximity to the surface, and therefore there would be danger of the threads, especially when fine threads are employed, being overlaid one upon the other and failing to make a perfect cop. To overcome this objection, I make use of a guide with a flat face through which the eye extends substantially at right angles and pivot or'otherwise secure the head of the guidethat is, the part having the eye or slotto the other portion, so that the said head will swing and accommodate itself at all times to the surface of the cop against which it is pressed by the action of the spring h. Thehead maybe movablyconnected to the body of the guide in various ways. I prefer, however, the construction shown in Figs. 1 and 2, where the head is provided with a vertical pin 1', fitting a socket or recess in the body of the guide, thereby permitting the head to swing to any desired extent to accommodate itself to the contour of the surface of the cop.

Of course it will be evident that the entire guide might be pivoted in any suitable manner upon its supports, or instead of being pivoted there might be a spring connection between one part of the guide and the other or its supports. Thus, as shown in Figs. 3 and 4, the head 0 of the guide may be connected to the frame 0 through the medium of a vertical flat spring 0 which will yield torsionally to permit the flat inner face of the head 0 to lie against thetapering surface of the cop.

I do not here claim the tapering cop described, as the latter is the subject of my application, Serial No. 466,922.

Vithout limiting myself to the precise construction and arrangement of parts shown, I claim- 1. The combination with the winding-shaft ofa winding-machine, of a reciprocatingguidc having a flat face, means for maintaining the guide with a yielding pressure in contact with the face of the cop being wound, and a connection between the head of the guide and its support whereby the said guide is self-adjusting to a position parallel to the face of the gop, substantially as and for the purpose set orth.

2. The combination with the winding-shaft and taperingholder, of a reciprocating guide supported to move to and from the holder, and with a flat bearing-face having an eye at right angles thereto, means for maintaining the guide in contact with the cop, and a connection between the guide and its support permitting the guide to turn laterally to automatically accommodate itself to the form of the cop, and maintain the said eye at right angles to the face of the cop, substantially as set forth.

3. The combination of the winding-shaft and reciprocating guide of awinding-machine, of means for varying the relative movements of the guide and the winding-shaft, the said guide having a flat face bearing on the cop and being supported to turn laterally to antomatically maintain its parallelism at all times with the face of the cop, substantially as set forth.

4. The combination in a winding-machine,

of the winding-shaft, a reciprocating frame, a guide supported by said frame and consisting of two sections, the upper section having a flat face and an eye or slot at right angles to said face and pivotally connected to the lower section, and means for maintaining the face of the guide in contact with the surface of the cop, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
